Orbit and dynamics

Between its closest point (0.829 AU) and its farthest (1.045 AU), the heliocentric distance changes by 0.216 AU over every revolution.

One full revolution takes 0.91 yr (331 days), computed from the semi-major axis of 0.937 AU.

An eccentricity of 0.116 makes the orbit moderately elongated.

A steep inclination of 47.66° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 34.5 km/s at perihelion and falls to 27.4 km/s at aphelion.

Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 21.95 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.14 km.

Observation record and orbit quality

Astrometry from 170 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4197 arcseconds.

Condition code U = 8 signals a poorly constrained orbit, so its future path should be treated as provisional.

About these computed values

Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
